Hi all:
I'm writing 'cause I need a suggestion about the best way to face an issue in a project.
I'm working in a big management system. In this struts application almost all pages have a lot of fields with a performance like a desktop application, specially with a lot of validations. The main problem is when, in many cases, I need to hide or disable some visual components according to the user actions over the page or the values selected in those components (check or uncheck of radios and checkboxes, value selected in a combo, etc) .To make this, I'm using javascript, but there are a lot of field values and/or names extracted from the data base (codifiers, entities properties, etc), wired to the javascript functions 'cause the page's performance depends on it (eg. if I select the value "Admin" in a combo, I need to hide Table1 and show Table2, but if I pick value "Operator" I need to hide both tables). I know this is a bad programming practice (using business logic in the view) and it doesn't allows to reuse the code, but I don't have any other idea to do this.
Any help is welcome,
Thanks in advance...

I have seen AJAXTags, but UITags thoes exactly what I need. The problem is that I can't get it work. I have follow all steps for configuration, and take a look at the samples.war, but it doesn't work to me. Have any of you any example or tutorial or can tell me how to use it with struts 1.1?
Thanks very much...

UI Tags is great!
But as simple to add some tags... consider http://ajaxtags.sourceforge.net
if you can't find something in UI Tags.

Thanks everybody for your comments. I can't use AJAX now 'cause the time is
short and the amount of changes will be a lot, but I will try uitags (I have
seen the demo and I liked it).
Thanks very much!

Consider using AJAX in your application.
AJAX is a good candidate when your app needs to behave like desktop
applications.

If AJAX is used wisely, business logic need not come into the view, also you
can reuse the code.
However AJAX primarily is JavaScript based.
Check this out: http://javawebparts.sourceforge.net/ (see AjaxParts)
Some articles on AJAX http://www.omnytex.com/articles/
Of course there are many other custom AJAX implementations as well.
If you do not want use JavaScript and still use AJAX,
http://ajaxanywhere.sourceforge.net
There must be some good design patterns/ or guidelines when using AJAX.
Has anyone here got some pointers to them??

If you don't want go AJAX, then try uitags.sf.net.
